The shifting ethnic and racial composition of the United States has social scientists and political strategists busy calculating the “new electoral math”. By 2040, Latinos will surpass 30% of the population, while whites will be a minority. A new study from the Pew Research Center suggests this could spell serious trouble for the GOP—children of Latino immigrants are more likely to lean Democrat than their parents.

Jody Agius Vallejo, a sociologist at USC, believes that the data is correct: Latino voters are going blue. She pushes back against the notion that the Latino vote will eventually break toward the Republicans due to “traditional values,” instead arguing that Republican policies like Arizona’s controversial SB1070 will continue to drive Latino voters to the left. She puts it bluntly:

Latinos are presently not attracted to the Republican party and there is no reason to think that Latinos will become Republicans just because a few Republicans support immigration reform.

Immigration reform figured prominently in both President Obama’s State of the Union address and Senator Marco Rubio’s GOP response. As the debate heats up in Congress, the increasing voting power of Latinos will certainly factor into how both major parties draw up their positions.
